贴片自恢复保险丝.doc

贴片自恢复保险丝 自恢复保险丝可分为贴片自恢复保险丝同插件自恢复保险丝，随着产品要求的越来越小型化，贴片保险丝的使用范围已越来越广泛。贴片自恢复保险丝主要封装有：0805、0603、1206、1812、2920，其工作原理为： 自恢复保险丝是由经过特殊处理的聚合树脂(Polymer)及分布在里面的导电粒子(Carbon Black)组成。在正常操作下聚合树脂紧密地将导电粒子束缚在结晶状的结构外，构成链状导电电通路，此时的可恢复保险丝为低阻状态(a)，线路上流经自恢复保险丝的电流所产生的热能小，不会改变晶体结构。当线路发生短路或过载时，流经自恢复保险丝的大电流产生的热量使聚合树脂融化，体积迅速增长，形成高阻状态(b)，工作电流迅速减小，从而对电路进行限制和保护。当故障排除后，PTC可恢复保险丝重新冷却结晶，体积收缩，导电粒子重新形成导电通路，自恢复保险丝恢复为低阻状态，从而完成对电路的保护，无须人工更换。
